CVE-2024-57214 is a command injection vulnerability identified in the TOTOLINK A6000R router firmware version V1.0.1-B20201211.2000. The vulnerability arises from improper input validation of the devname parameter within the reset_wifi function. Command injection (CWE-77) allows an attacker to inject and execute arbitrary system commands on the affected device. The vulnerability is remotely exploitable over the network (Attack Vector: Network) without requiring privileges (PR:N), but it does require user interaction (UI:R), such as tricking a user into triggering the vulnerable function. The vulnerability impacts confidentiality, integrity, and availability, as arbitrary command execution can lead to unauthorized data access, modification, or denial of service. The CVSS v3.1 base score is 6.3 (medium), reflecting the moderate risk. No patches or mitigations have been officially released at the time of publication, and no known exploits have been observed in the wild. The TOTOLINK A6000R is a consumer and small office/home office (SOHO) router, commonly deployed in various regions, making this vulnerability relevant to a broad user base. The vulnerability highlights the importance of secure input validation in embedded device firmware to prevent command injection attacks.

The potential impact of CVE-2024-57214 is significant for organizations and individuals using the TOTOLINK A6000R router. Successful exploitation could allow attackers to execute arbitrary commands remotely, leading to unauthorized access to network infrastructure, data leakage, or disruption of network services. This could result in compromised confidentiality, integrity, and availability of network communications. For small businesses and home users relying on this router, exploitation could lead to network downtime, interception of sensitive information, or use of the device as a foothold for further attacks within the network. Although no active exploits are currently known, the presence of this vulnerability in widely deployed consumer routers increases the risk of future exploitation, especially if attackers develop automated tools. The lack of an official patch further elevates the risk until remediation is available. Organizations with TOTOLINK devices in their network perimeter should consider the threat seriously, as attackers could leverage this vulnerability to bypass network defenses or disrupt operations.

To mitigate CVE-2024-57214, organizations and users should take the following specific actions: 1) Immediately restrict access to the router’s management interface by limiting it to trusted internal networks and disabling remote management if not required. 2) Monitor vendor communications closely for firmware updates or patches addressing this vulnerability and apply them promptly once available. 3) Employ network segmentation to isolate vulnerable devices from critical infrastructure to reduce potential impact. 4) Implement strict input validation and filtering at network boundaries to detect and block suspicious command injection attempts targeting the devname parameter. 5) Educate users about the risks of interacting with unsolicited prompts or links that could trigger the vulnerability, reducing the likelihood of user interaction exploitation. 6) Consider deploying intrusion detection/prevention systems (IDS/IPS) with signatures targeting command injection patterns specific to this vulnerability. 7) As a temporary measure, rebooting the device may clear any injected commands but does not fix the underlying issue. 8) Evaluate alternative hardware or firmware solutions if timely patches are not forthcoming, especially in high-risk environments.
